Overheard between the two un-toilet trained two year olds:
"Do you poop in the potty?"
"Yeah, I poop in the potty."
"Sometimes I poop in the potty and sometimes I poop in my pants."
"I poop in my pants."
"I poop in my pants all the time!"
Writing it, it isn't really as funny. But it was hilarious as they were having this conversation the truth came out and they walked away bonded over the fact that neither of them was anywhere near getting the whole concept! (Or at least caring!)
